Bob authorizes his mortgage lender to make automatic ACH payments from his bank account. This starts an information flow as Bob's bank checks for sufficient funds and debits his account if funds are available, sending the payment details to the ACH operator. The ACH operator then debits the receiving bank and credits the mortgage lender's account, completing the multi-step process. While simple for users, the ACH system involves many institutions and can be inefficient, and international payments are even more complex. CoinPip aims to simplify international payments with their service.
